| 中文摘要 | an ethylene-propylene copolymer (epm) was functionalized with an iso cyanate-bearing unsaturated monomer, allyl(3-isocyanate-4-tolyl) carbamate (tai), with dicumyl peroxide as an initiator in a xylene solution. fourier transform infrared (ftir) was used to confirm the formation of epm-g-tai. the peak at 2273 cm(-1), characteristic of -nco groups in epm-g-tai, revealed evidence of grafting. the grafting degree was determined with both chemical titration and ftir. the grafting degree could be adjusted, and the maximum was over 6 wt % without any gelation. the molar mass distribution of epm-g-tai was narrower than that of epm. the rheological behavior of both epm-g-tai and epm was investigated with a rotational rheometer. the apparent viscosity of epm-g-tai was higher than that of epm and increased with an increasing grafting degree of tai. surface analysis by contact-angle measurements showed that contact angles of epm-g-tai samples to a given polar liquid decreased with an increasing grafting degree of tai. we also obtained the dispersion component of the surface free energy (gamma(s)(d)), the polar component of the surface free energy (gamma(s)(d)), and the total surface free energy (gamma(s) = gamma(s)(d) + gamma(s)(p)) of the grafted epm. these parameters increased with the enhancement of the grafting degree, which gave us a quantitative estimation of the polar contribution of the grafted tai to the total surface free energy of epm-g-tai. |
